Engine build issue: CAS shaft hitting ARP head stud

[maxhag]

Ok, well I am getting towards the end of the motor I am building. (4AGTE)

But, just hit a snag.....

I have got up to the point of fitting up the CAS. I can't get the CAS fully in, because the end of the CAS shaft is hitting the ARP head stud, the ARP studs look like they sit higher than factory head bolts.

See pic:





Here you can see the gap size between the CAS and the head:





Is this a common problem?
Something not compatible?

I got a distributor too, and that fits fine because the shaft is not as long........

Any help appreciated.....

Thanks.

[Hen may possibly be a nut]

Never heard of it before, but just cut the shaft. Everything beyond the teeth (or pin, can't remember which comes last) is just excess weight.

[maxhag]

yeah, that could work. Thanks Hen.. The pin/s are last BTW....

[Sam-Q]

I know of this, the guy I spoke to cut a small notch out of the bolt I think

Yes, fairly common problem. Both solutions are fine.

Take it off the shaft. I usually just grind it almost flush with the gear and then bevel it a bit with a file in-case you need to remove it to rebuild the CAS.

x11ty to all these solutions.
although i ran mine for a period (was unaware it was fouling) with no ill affect. but as andrew has said ive had my CAS shaft shaved and chamfered to suit.

I had the same problem with my distributor. Just hack sawed the end of the shaft off. 1000km's later and no problems.

This has happened to me a few times. Cut the end of the cas of and ground it down till it had clearence.
